PATENT- DEVICE FOR REClPROCATlNG THE DRAWING-OFF ROLLS OF COMBlNG-MACHlNES.

SPECIFICATION forming part of Letters Patent No. 414,884, dated November 12, 1889. Application filed April 27, 1889. Serial No. 308,845. (No model.) Patented in England Janua y 23, 889,

To all whom it may concern.-

Be it known that L'FREDERIOK ILLING- WORTH, a subject of the Queen of Great Britain and Ireland, residing at Bradford, in the county of York, England, have invented certain new and useful Improvements in Devices for Reciprocating the Drawing-Off Rollers of Oombing-Machines and the Like, (for which I have obtained Letters Patent in England, No. 1,212, datedvJanuary 23, 1889,) of which thefollowing is a specification.

This invention relates to the drawing-01f rollers-for combing-machines, andis particularly applicable to that class of machines known as Nobles combs, but is also applicable to other classes of combing-machines in which circular combs are used, and has for its object the distribution of the wear and tear over a moreextended portion of the fluted part of the rollers for drawing the fiber from the comb-circles than is the case when mounted and operated in the usual manner. With drawing-off rollers arranged as is now the common practice the wear and tear are thrown upon one portion of the rollers,which is found in practice to be confined to about half an inch only of the full length of the fluted part, which is soon cut away by the fiber to such an extent that the rollers are useless even when made of steel and hard ened.

In describing my invention more in detail reference is made to the accompanying drawings, in which Figure 1 represents a View of a pair of drawing-off rollers having my operating apparatus connected thereto and a part of a circular comb. Fig. 2 is a plan below the line Z Z of Fig. 1; Fig. 3, a view of a part of the apparatus, looking in the direction of arrow 1; Fig. 4, a similar View looking in the direction of arrow details.

The fluted drawing-off rollers 'A and A are mounted upon the frame of the comb, With their journals longitudinally or endwise movable in their hearing in or on brackets T, and driven by the spur-wheel B, connected by the usual train of gearing to the driving-shaft 2, and Fig. 5 shows detachedin the ordinary manner, to which no claim is made.

In order to distribute the wear upon the surface of the flutedrollers A and A, I operate the said rollers in the direction of their axis, in addition to the usual rotary motion, by combining with each pair of fluted rollers an apparatus secured to some convenient portion of the frame-work of a combing-machine. The said apparatus or endwise operating mechanism is carried by a bracket D, and on the driving-spindle S of the fluted roller A, which spindle, with its pinion B, is longitudinallymovable with its roller, is secured a worm E, which gears with a wheel F, secured on a shaft G, on which is also secured a worm H, gearing into wheel J, to which is attached a spur-wheel K, both mounted on a vertical stud. The last-mentioned wheel is in gear with a spur-wheel L, to which is secured a worm M, both being mounted on a stud, and the Worm M, in gear with a wheel N, supported on a stud carried by the before-mentioned bracket D. In the plate of the lastnamed wheel N is formed a slot q, in which is secured a pin Q of such length as to extend into a slot 0, formed in' the saddle R, prepared with two flanges f f, that extend to.

and embrace the driving-spindle S of the fluted roller A, and between the said flanges on the spindle S is secured the first-mentioned worm E, so that as the wheel N rotates the adjustable pin Q, will slide in the slot 0" of the saddle R, thereby causing it and the rollers A and A to move longitudinally to and fro through the bearings in the roller-brackets T, the roller A being moved by the worm E, secured between the before-mentioned flanges and the roller A by one end of the spindle resting on the top flange fof the saddle B, said spindle being formed with a recess at A into which fit the arms of a slotted clip U, as shown by plan'view, Fig. 2, the said clip being bolted to the saddle. Thus by these arrangements both revolving rollers A and A are made to slide longitudinally in their bearings, and thereby utilize a more extended length of the fluted part of the rollers for drawing the fiber from the comb-circles.

hat I claim is In testimony whereof I have signed my name lhe combination of The rolls A A an cl their to this specification in the presence of two sub- [0 spindles, the worm E, secured on the spindle scribing witnesses. of one of said rolls with the sadclle R, FREDERICK ILLING\V()R'III'. intervening WOIIHS and Wheels and the slotted elip U, all arranged substantially in the man- \Vitnesses: ner and for the purpose as hereinbefore set \VM.
